The study aimed to determine how well recorded pain levels and range of motion relate to patients' reported levels of functional ability/disability pre- and post- total hip arthroplasty. Range of motion (ROM), Oxford Hip Score (OHS) and Self-Report
Aim. The objective of this study was to evaluate the intermediate term clinical and radiological results of a new short stem hip implant. Methods. In 20 consecutive patients suffering from osteoarthritis with 25 affected hip joints (five cases were bilateral), the clinical and radiological results of 25 hip arthroplasties performed in one hospital between October 2009 and May 2014 through a minimally invasive anterolateral approach using a cementless short stem prosthesis type Aida and a cementless cup type Ecofit with a ceramic on ceramic pairing were evaluated prospectively. The median age of patients at time of surgery was 60 years (range, 42–71 years), 15 male (4 were bilateral) and 5 female patients (one was bilateral) were included in the study. The median clinical follow up was 30 months (range, 2–88 months), and the median radiological follow up was 30 months (range, 2–88 months). Results.
Although day surgery has a good patient satisfaction and safety profile, accurate episode-of-care costs (EOCC) calculation for of this procedure compared to standard same-day admission (SDA), while considering functional outcomes, is not well known. This study assesses the EOCC for patients with a THA while comparing DS and Same Day Admission (SDA) (with a 1-day hospitalization) pathways. The episode-of-care cost (EOCC) of 50 consecutive day surgery and SDA patients who underwent a THA was evaluated. The episode-of-care cost was determined using a bottom-up Time Driven- Activity Based Funding method. Functional outcomes were measured using preoperative and postoperative
Paget's disease of bone (PDB) is characterised by increased bone resorption and development of an erratic bone structure that is highly fragile and susceptible to fracture. In addition, altered joint biomechanics lead to arthritis, more often in the hip and pelvis, resulting in disability and a Total hip Arthroplasty (THA) may be required. THA in PDB is associated with more complications compared to normal population. There is no consensus on the type of arthroplasty that performs better in people with PDB. To our knowledge, there is no meta-analysis in literature on this rare problem. We undertook a systematic review and meta-analysis to compare the effectiveness of cemented versus cementless THA in patients with PDB. PRISMA guidelines were followed. Search strings were generated based on Boolean operators for identification of the reference articles. 31 studies were included overall. Revision rate was lower in the cementless group compared to the cemented group (chi square=4.36, p=0.04), aseptic loosening was lesser in the cementless group compared to the cemented group (chi square=4.13, p=0.04). The type of the arthroplasty did not affect the infection rate (chi square=2.51, p=0.11), pre and post op
Abstract. INTRODUCTION. Fracture neck of femur is aptly called as “the fracture of necessity” owing to the various factors responsible for its non-union. Pauwel's inter-trochantric valgus osteotomy is a useful approach to deal with such fractures. AIM. The aim of this study is to evaluate the functional outcome of valgus osteotomy in treatment of neglected and non-union fracture neck of femur using Harris Hip Scoring system (HHS). MATERIAL AND METHODS. This observational study included 25 patients of the age between 25 years and 50 years with more than 3 weeks since injury and the patients with failed primary fixation. Valgus osteotomy using120° double angled blade plate was done. The patients were followed up till one year. The patients' functional outcome was evaluated with pre-operative and post-operative
Abstract. Background. Although tantalum is a well recognised implant material used for revision arthroplasty, little is known regarding the use of the same in primary total hip arthroplasty. Methods. A literature search was performed to find all relevant clinical studies until March 2020, which then underwent a further selection criteria. The inclusion criteria was set as follows: Reporting on human patients undergoing primary total hip arthroplasty; Direct comparison between tantalum acetabular cups with conventional acetabular cups. for use in primary total hip arthroplasty; Radiological evaluation (cup migration, osteointegration); Clinical (functional scores, need for subsequent revision, patient-reported outcomes; Post-operative complications; Reporting findings in the English Language. After a thorough search a total of six studies were included in the review. The primary outcome. measures were clinical outcomes, implant migration, change in bone mineral density and rate of revision and infection. Results. Tantalum was found superior to titanium with regards to fewer radiolucencies, survivorship, osteointegration, decreased osteolysis and mechanical loosening. No significant difference in radioisometric analysis, bone mineral density or
THA in patients with acetabular bone defects is associated with a high risk of dislocation. Dual mobility (DM) cups are known to prevent and treat chronic instability. The aim of this study was to evaluate the dislocation rate and survival of jumbo DM cups. This was a retrospective, continuous, multicenter study of all the cases of jumbo DM cup implantation between 2010 and 2017 in patients with acetabular bone loss (Paprosky 2A: 46%, 2B: 32%, 2C: 15% and 3A: 6%). The indications for implantation were revisions for aseptic loosening of the cup (n=45), aseptic loosening of the femoral stem (n=3), bipolar loosening (n=11), septic loosening (n=10), periprosthetic fracture (n=5), chronic dislocation (n=4), intraprosthetic dislocation (n=2), cup impingement (n=1), primary posttraumatic arthroplasty (n=8), and acetabular dysplasia (n=4). The jumbo cups used were COPTOS TH (SERF), which combines press-fit fixation with supplemental fixation (acetabular hook, two superior flanges with one to four screws, two acetabular pegs). A bone graft was added in 74 cases (80%). The clinical assessment consisted of the
Introduction. Snapping hip syndrome is a common condition affecting 10% of the population. It is due to the advance of the iliotibial band (ITB) over the greater trochanter during lower limb movements and often associated with hip overuse, such as in athletic activities. Management is commonly conservative with physiotherapy or can be surgical to release the ITB. Here we carry out a systematic review into published surgical management and present a case report on an overlooked cause of paediatric snapping hip syndrome. Materials & Methods. A systematic review looking at published surgical management of snapping hip was performed according to PRISMA guidelines. PubMed, MEDLINE, EMBASE, CINAHL and the Cochrane Library databases were searched for “((Snapping hip OR Iliotibial band syndrome OR ITB syndrome) AND (Management OR treatment))”. Adult and paediatric published studies were included as few results were found on paediatric snapping hip alone. Results. 1548 studies were screened by 2 independent reviewers. 8 studies were included with a total of 134 cases, with an age range of 14–71 years. Surgical management ranged from arthroscopic, open or ultrasound guided release of the ITB, as well as gluteal muscle releases. Common outcome measures showed statistically significant improvement pre- and post-operatively in visual analogue pain score (VAPS) and the
Hip instability is one of the most common causes for total hip arthroplasty (THA) revision surgery. Studies have indicated that lumbar fusion (LF) surgery is a risk factor for hip dislocation. Instrumented spine fusion surgery decreases pelvic tilt, which might lead to an increase in hip motion to accommodate this postural change. To the best of our knowledge, spine-pelvis-hip kinematics during a dynamic activity in patients that previously had both a THA and LF have not been investigated. Furthermore, patients with a combined THA and LF tend to have greater disability. The purpose was to examine spine-pelvis-hip kinematics during a sit to stand task in patients that have had both THA and LF surgeries and compare it to a group of patients that had a THA with no history of spine surgery. The secondary purpose was to compare pain, physical function, and disability between these patients. This cross-sectional study recruited participants that had a combined THA and LF (n=10; 6 females, mean age 73 y) or had a THA only (n=11; 6 females, mean age 72 y). Spine, pelvis, and hip angles were measured using a TrakSTAR motion capture system sampled at 200 Hz. Sensors were mounted over the lateral thighs, base of the sacrum, and the spinous process of the third lumbar,12th thoracic, and ninth thoracic vertebrae. Participants completed 10 trials of a standardized sit-to-stand-to-sit task. Hip, pelvis, lower lumbar, upper lumbar, and lower thoracic sagittal joint angle range of motion (ROM) were calculated over the entire task. In addition, pain, physical function, and disability were measured with clinical outcomes: Hip Disability Osteoarthritis Outcome Score (pain and physical function), Oswestry Low Back Disability Questionnaire (disability), and
Introduction. Torsional deformities of the femur have been recognized as a cause of femoroacetabular impingement (FAI) and hip pain. High femoral antetorsion can result in decreased external rotation and a posterior FAI, which is typically located extraarticular between the ischium and trochanter minor. Femoral osteotomies allow to correct torsional deformities to eliminate FAI. So far the mid-term clinical and radiographic results in patients undergoing femoral osteotomies for correction of torsional deformities have not been investigated. Objectives. Therefore, we asked if patients undergoing femoral osteotomies for torsional deformities of the femur have (1) decreased hip pain and improved function and (2) subsequent surgeries and complications?. Methods. We retrospectively evaluated 21 hips (18 patients) who underwent femoral osteotomies for correction of torsional deformities between April 2005 and October 2014. Twenty hips with excessive femoral antetorsion (47.7° ± 8.6°, range 32° – 65°) had a derotational femoral osteotomy. One hip with decreased femoral antetorsion of 11° underwent rotational femoral osteotomy. Previous surgery were performed in 43% of the hips including hip arthroscopy (5 hips), acetabular osteotomy (2 hips), open reduction for high dislocation (2 hips), surgical hip dislocation (2 hips) and varus intertrochanteric osteotomy (1 hip). In 10 hips a concomitant offset correction and in 5 hips a concomitant periacetabular osteotomy were performed. The mean followup was 3.6 ± 2.3 (1 – 10) years. One patient (one hip) died from a cause unrelated to surgery at the 2 year follow-up. We used the anterior and posterior impingement test to evaluate pain. Function was assessed using the Merle d'Aubigné Postel score, WOMAC, UCLA activity score and
INTRODUCTION. Uncemented total hip replacement is on the rise worldwide. Latest studies from various European and other developed country joint registers are clearly showing that it is taking preference over the cemented joint replacements. These figures were discussed most recently at the London hip meeting. Our study is related to one single make of implant the Exceed hip (Biomet) at two hospitals in Northamptonshire, Kettering UK. MATERIAL & METHODS. Our series includes 256 cases of Exceed uncemented total hip replacement done in 236 patients with a minimum follow up of 6 months and maximum of 5 years. The study included 126 female and 110 male patients. Out of this number 121 cases were done at Kettering General Hospital and 135 cases were performed at Woodlands Hospital private limited in Kettering. The cases were performed by 2 senior consultants and one junior consultant. The total number of cases was 317 but 73 cases were lost to follow up and 2 patients had expired at the time of the study. In all cases pre operative and post operative
Introduction. Collapse of femoral head associated with end-stage arthritis form hallmark of osteonecrosis of femoral head. Purpose was to assess efficacy of platelet rich plasma following core decompression in early stage of osteonecrosis of femoral head. Methods. Forty consecutive age, sex and BMI-matched patients of osteonecrosis were enrolled for this prospective randomized comparative double blinded clinical study. 19 patients belonged to intervention group (PRP with Core decompression) and 21 to control (Core decompression) group. 8ml of autologous PRP was injected into channels alongwith Calcium Chloride (4:1) after core decompression. Patients were assessed for outcome measures by pain score, functional and
BACKGROUND CONTEXT. Ceramic bearings are widely used in total hip arthroplasty (THR) along with metal and polyethylene bearings. There were several studies in past few years evaluating the advantage of one over the other. The young population with high activity levels has an increased risk of wear debris production at bearing surface and subsequent implant failure. Recently, interest and use of a ceramics with high wear resistance has been growing. Early reports on ceramic on ceramic THR have demonstrated excellent clinical and radiological results. PURPOSE. To evaluate clinical, functional and radiological outcomes of cement-less ceramic on ceramic primary total Hip Replacement (THR) in young patients (<50 years age) with diagnosis of avascular necrosis femoral head. STUDY DESIGN. Single - centre, prospective comparative study of prospectively collected outcomes, with a minimum of 12 month follow-up. PATIENT SAMPLE. 30 patients who underwent cement-less ceramic on ceramic primary THR in young patients (< 50 years age) for avascular necrosis of femoral head. OUTCOME MEASURES. For clinical evaluation,
Purpose. We evaluated the clinical and radiographic outcomes of cementless bipolar hemiarthroplasty using rectangular cross-section stem for femoral neck fracture in elderly patients more than 80 years of age with osteoporosis. Material and Methods. 76(cemented 46, cementless 30) bipolar hemiarthroplasties for femur neck fracture were performed in elderly patients more than 80 years old. The mean follow-up period was 4.3 years (2 to 7 years). The
Introduction. Primary robotic-arm assisted total hip arthroplasty (THA) yields more accurate and reproducible acetabular cup placement, nonetheless, data is scarce in terms of outcomes. The purpose of the present study was to report on patient-reported outcomes (PROMs) in a large group of patients who underwent robotic-arm assisted THA. The authors hypothesized that (1) patients who underwent robotic-arm assisted primary THA would achieve favorable and significant improvement in PROMs, (2) an accurate and reproducible acetabular cup placement with respect to the defined SafeZones would be obtained, and (3) a low rate of THA dislocation would be observed. Methods. Prospectively collected data were retrospectively reviewed between April 2012 to May 2017. Primary THA using Mako Robotic-Arm [Mako Surgical Corp. (Stryker), Fort Lauderdale, FL, USA] with minimum two-year follow-up for the
The purpose of our study was to prospectively examine early functional differences in gait between the direct anterior and direct lateral surgical approaches for total hip arthroplasty over the first three months postoperatively. Forty participants were prospectively enrolled to either the direct anterior (20 patients) or direct lateral group (20 patients) based on their surgeon's expertise. Outcome measures were collected preoperatively at their preadmission appointment and postoperatively at discharge from the hospital, two weeks, six weeks and three months. We used the GAITRite® system to measure gait velocity, stride length, single-limb support and single-limb support symmetry. We also had participants complete the Timed Up and Go test and a series of questionnaires at each visit: WOMAC, SF-12,
Background. Total hip arthroplasty (THA) has been and continues to be the gold standard for treatment of end-stage osteoarthritis. With each year, implant characteristics are evolving to increase patient-reported outcomes and decrease complications. Purpose: to report minimum 2-year outcomes and complications in patients who underwent robotic-arm assisted THA using Corin versus Stryker-type implants. Methods. Data were prospectively collected on patients who underwent THA with Corin-type implants (both cup and stem) and THA using Stryker implants between June 2011 and July 2016. A 1:1 propensity match was performed using the following 5 covariates: age, body mass index, gender, Charlson score and smoking status. Surgical outcomes were assessed at minimum 2-year follow-up using the Forgotten Joint
Purpose. The purpose of this study is to evaluate the clinical outcomes and and radiological findings of primary total hip arthroplasty(THA) performed by using cemented polished femoral stem. Materials and Methods. We retrospectively reviewed 91 hips (84 patients) that had undergone primary THA with cemented polished femoral stem after follow-up more than 10 years. The mean age at surgery was 57 years old (47 to 75). Mean follow up period was 12. 8 years(10.1 to 14). Clinical evaluation was performed using
Introduction & aims. Total hip replacement is an excellent treatment option for people with late stage degenerative hip disease. In addition to marked reduction in pain and improvement in sleep, most people regain range of motion, physical ability and quality of life. This study aimed at the functional outcomes of large diameter heads in THR patients. Method. This study is an analysis of a cohort of patients undergoing total hip replacement performed at our hospital from November 2011 to July 2013. A total of 70 hips, 40 males and 30 females, were operated upon with large diameter femoral heads. The mean age was 50.38 years (range 40–59 years). In our cohort, 32 patients had AVN of femur head, 19 had post traumatic secondary degeneration, 10 had RA, 6 had AS and 3 patients had OA of hip. The follow-up data included local complications,
Short-stem total hip arthroplasty (THA) has primarily been recommended for young and active patients, mainly due to its bone preserving philosophy. Elderly patients, however, may also benefit of a minimally invasive technique due to the short and curved implant design. The purpose of this study was to compare the clinical and radiological outcomes as well as perioperative complications of a calcar-guided short stem between a young (75 years) population. Data were collected in a total of 5 centers, and 400 short stems were included as part of a prospective multicentre observational study between 2010 and 2014 with a mean follow-up of 49.2 months. Clinical and radiological outcomes were assessed in both groups. Secondary outcomes such as perioperative complications, rates and reasons for stem revision were also investigated. No differences were found for the mean visual analogue scale (VAS) values of rest pain, load pain, and satisfaction.
